A more thorough explanation:

Definition: Expectation is the act of looking forward to something or anticipating it. It can also refer to the prospect of receiving something, like wealth or honors.

For example, a student may have the expectation of receiving good grades if they study hard. Or, a person may have the expectation of getting a promotion at work if they perform well.

It's important to note that expectation does not always mean intention. For instance, a surgeon may expect that their patient will die during an operation, but they do not intend for that to happen. They intend for the patient to recover, but they are aware that the outcome may not be what they hope for.

Overall, expectation is a feeling of hope or belief that something will happen or be received in the future.
